Thus in the case of the narrow straw-like ribbon it is necessary to ii'rst glue together a series of threads and then to dry this glued bundle while keeping it of constant length. In alike manner, in the well-known processes for the production of artificial silk it is necessary to subject the threa-ds successively to a'large number of processes and to keep them constantly under tension durmg known hitherto for the production of such threads involve a more or less discontinuous operation, the thread being delivered to reels or sppols the material of which mustbe adapt,- ed to the operation for these processes, that is tosay,

to conduct the thread successively through the several processes without resorting to? new spooling or new reeling. In most cases attempts of this character fail because the f'iaea uww we.

i The present invention enables t e great length of the "thread to be brought'into the "shape of a spiral and thus to render the entire apparatus exceedingly compact and The principle of the operation to be performed by the device described hereinafter consists in winding the thread upon a drum like rotating body and at the same time shifting it laterally in the direction of the drums longitudinal axis in such a manner that theithread is always wound in a plane and unwound in a parallel plane located laterally thereof, witnout'requiring a separate second drum with laterally shifting rods and without any crossing and tangling iof the threads. In principle this is accomlplished by constructing a winding drum ;with two sets ofrods one within the other. i In the accompanying drawings, I have grepresented several. examples of my invention. Figure 1 is aside elevation of one form of "-my winding device,- with parts in'section;

Ia companion head and-with orient-the v iii Fig. 16 is a cross section showing two sets of windin rods provided with curved attached strips; and Figs. 17 and 18 are a side elevation and a cross section respectively, of a peculiar 'I-shaped rod which may be used in my improved winding de vice.

In the form of my invention illustrated by Figs. 1 to 6, I employ two sets of parallel rods, the rods of the same set being at the same distance from a common center or axis, or in other words, the rods of each set are arranged upon a cylindrical surface, as it were. One of these sets is of constant diameter; its rods, designated by II, are secured to disks 0. At points midway between the rods II, the disks C- are provided with slots or notches 0 extending radially inward from the periphery. Through these notches extend at all times (see Fig. 3) the rods I of the movable set. The ends of these rods are received in cam grooves e of the heads d. These grooves vary not only as to distance from the center or axis (Fig. 5 but also in depth (Fig. 6) and are therefore adapted to move the rods 'I in or out radially,'and also lengthwise, that is, parallel with the axis.

In the position shown in Fig. 8, a thread them are rotated in unison, by means of the shaft Z to which they are. secured rigidly. The rods-II therefore have no movement above in connection with the'rods' I. The

shaft Z is driven in any suitable -manner for instance by means of a pulley m. On the shaft Z is also secured rigidly a gearwheel h meshing with a pinion 2' on a c'ountershaft' s" which carries alikepinion at the other end. The two pinions d are in mesh with gear wheels" 9 on bosses ,t which are' integral or rigid with the camheads at. One of these being employed chiefly to obtain a greater certainty of movements, and to facilitate removal and renewal of the rods I.

The two pinions a are alike, as are the gear wheels g, so that both heads 03 will revolve at the same speed. i The wheel it however has a. number of teeth different from the wheels g, so that by the diflerential gearing the heads d are given a difi'erent number of revolutions from the shaft Z, and disks C. With each set comprising twelve rods, as shown, I prefer to have the gearing so constructed that for a complete revolution of the drum, the disks (i will lag behind the disks C just one-twelfth of the circumference in each rotation. This may be accomplished by providing the gears g with a less number of teeth than gears h whereby the gears 9 will be rotated at a faster rate than gears h. The differential movement of the disks 0? and C provides for a relative move ment between the ends of the rods I and the bottoms and side of the cam-grooves 6 whereby the rods are operated, as herein after described. T

In the operation of thisdevice, the thread travels to the drum always in the same plane, say that indicated by A-A in Fig. 1,

and always leaves in a plane parallel thereto, say the plane B-B. In detail, the operation is as follows: The thread arriving at A--A is received upon the rods II of the drum, and the rods I move outward in the notches c (owing to the action of the cam grooves 6) until they are farther from the axis than the rods II. The thread therefore, at this moment, is supported exclusively by the rods I. While the latter are thus in their outer position, they are moved lengthwise, that is, axially (toward the right in Fig. 1) so as to shift the thread to the plane BB. Then the rods I move inward to a position nearer theaxis than the rods II, thereby transferring the thread from the rods I to the rods II, The'rods I, while in their inner position and therefore out of contact with the thread, move lengthwise or axially in the opposite direction (to the left in Fig. thus bringing them back to their original position. It will be understood that both setsof rods I and II rotate in unison, the rods I being always within the notches 0 and therefore carried along by the disks C so'far as rotation about the axis of the drum 'is concerned. While the rpds II' have only this rotary movement, the rods I have two kinds of additional movements, viz: first, a contracting and expandlng movement within the notches 0, so that the diameter of the set' 10. The shaft Z is shown as extending 130 through the entire drum, with teal disks G secured to it. Each disk C (Fig. has peripheral radial slots or notches 0' for the rods I and II, that is to say, with twelve rods in each set (as before) there will be twenty-four notches instead of twelve. The rods'of both sets are movable in and out in these notches, their position being controlled by cam grooves e in the heads-d. Fig. 9 shows that when the rods I are in their outermost position the rods II are in their innermost position. The operation will be substantially the same as described above, so.

that a repetition of details will not be necessary. With this construction, ifthe cam grooves e are given the proper shape, 1t becomes possible to avoid entirely any'stretch- 4 ing of the thread during the operation. If it is desired to give the thread the same amount of lateral displacement as. in the construction first described, the lag of the cam heads 01 relatively to the notched disks C, for one revolution of the drum, ought to be The otherparts of Figs. 7 and 8 are of the same construction as in'Figs. l to 6 and are designated by the same reference letters. It will be noted that the spring is not employed in Figs. 7 to 10.

In Figs. 1 to lO'the endwise movement of the rods is obtained byemploying a cam groove of varying depth. According to Figs. 11 to 15, one of the heads d is provided with an extension 0 having a cam groove 7) upon a cylindrical surface, said groove receiving the ends of pins 9 secured to the rods I. The lateral deviations of the groove 72 (shown best in Fig. 14:) will give the rods the desired en'dwise movement. By. this arrangement the wear at the ends of the rods is prevented, since they need not engage the bottom of the cam groove e which controls the radial movement of the rods as before. Furthermore, the accuracy of the movement is,increased, even without the use of a spring. With this construction, in order to prevent rotation of the rods about their own axes, they are guided by means of pins 1, secured to the respective rods and fitted into radial slots 0' (Fig. 10) of the disks C. the main shaft Z is made hollow in order to convey hot air for drying or humid air for moistening purposes.

In the drawings described so far, the rods -I and II are shown simply as round rods.

This has been done for the sake of simplicity and of clearness. In practice, however, it is preferred to secure upon these rods, curved strips S of any suitable material such as rubber or metal (Fig. 16), so that the rod and strip together will constitute a rod having a T-shaped cross section, or instead of this, the body of the rod R itself may be given a T-shaped cross section, as

As indicated in Figs. 11 and 12,

shown in Figs. 17 and 18. If during the operation .of the device as described above, it should be thought desirable to alter the ten sion ofthe thread, this may be accomplished by increasing or reducing the diameter of the drum. For this purpose, the rods may be bent (as indicated in Fig. 17) to give the drum a differentdiameter, or rods of different diameters may be used. 1 Various modifications may be made without departing from the nature of my invention as set forth; in the appended claims.
